Patent ES-486635-A1 (ES)
Title: Device for feeding paper to a cylindrical roller printing-platen.
IPC: B41J13/16
Filed: 1979-12-06
Abstract: Apparatus for facilitating printer paper feeding. The apparatus is made up of a yoke and a platen channel carrying a paper aligner and feed rollers. The yoke has downwardly extending legs with a detent therebetween. The apparatus is rotatably positionable on a rod mounted parallel to the platen, and the detent is for accepting the rod. The downwardly extending legs are for cooperating with a tooth of a rotatable comb for causing rotation of the apparatus on the rod. The channel serves as a paper deflector and guide for guiding paper about the platen. Within the channel are openings through which front and rear feed rollers carried by the channel extend. Also within the channel is an aligner opening for accepting the paper aligner which is positionable within the aligner opening. The paper aligner has a downwardly extending leg for cooperating with another tooth on the comb to position the aligner within the aligner opening. Due to the structure of the apparatus, a member thereof can be utilized and positioned on the rod to accommodate any length platen.

Title: Versatile process for generating chlorine dioxide
IPC: C01B11/02
Filed: 1979-12-18
Abstract: An improved process is provided for the production of chlorine dioxide and chlorine wherein a chlorine dioxide generator may be operated interchangeably in either sulfuric acid or hydrochloric acid mode without changing acidity levels or evacuating the liquor of one mode and refilling with liquor of the second mode before continuing generation. The versatile process for production of chlorine dioxide comprises maintaining saturated solutions of both alkali metal chloride and alkali metal sulfate in the generator at an acid normality of from about 2 to about 11 in the presence of a small amount of catalyst selected from the group consisting of vanadium pentoxide, silver ions, manganese ions, dichromate ions and arsenic ions. Thus, the instant process provides high yields of chlorine dioxide even at high acidities making it possible to manufacture balanced quantities of saltcake and alkali metal chloride by-products as may be required.

Title: Needle assembly with vein entry indicator.
IPC: A61B5/15
Filed: 1982-02-24
Abstract: A needle assembly preferably suitable for single sample blood collection and for determining vein entry when collecting a blood sample from a patient into a vacuum collection device.
